[Effect of long-term electric stimulation of the head of the caudate nucleus on alimentary secretory reflexes in dogs].

In chronic experiments on dogs with implanted electrodes prolonged (30 min) subthreshold (20-30 mca) low-frequency (1 imp/sec) stimulation of the dorsal part of the caudate nucleus head inhibited the achievement of conditioned secretory alimentary reflexes. High frequency (100 imp/sec) stimulation under the same experimental conditions facilitated conditioned and unconditioned alimentary secretory reflexes. Under the influence of stimulation--high-frequency stimulation in particular--of the dorsal part of the caudate nucleus head differentiation inhibition tends to disinhibition.
